1.  The water cycle is when water evaporates from the sea, rivers, lakes and waterbeds etc.  It goes up into the atmosphere as water vapour.  The water vapour/water droplets cling together to form clouds.  Once the clouds get too heavy or there is too much water, it rains.  It's a continuous cycle. Sometimes it comes out as hail, snow or sleet.
2.  Cumulus, stratus and cirrus.  Cumulus clouds are puffy and large, clearly visible in the sky.
Stratus clouds and like large sheets in the sky, usually seen when it's a cloudy day or overcast.
Cirrus clouds are thin, wispy streams of cloud, usually seen on a nice day.
3.  Isobars are lines on maps that are connected and indicate that the  pressure in the atmosphere is the same.
4.  Low pressure systems make rain by low pressure areas forcing wind inwards.  These winds push the warm air up like a funnel and cool air rushes in to replace it.  As the warm air rises it cools, forming water vapour and then clouds, then rain happens.
5.  Lightning happens as electrical energy begins to build up in thunderclouds as small ice particles lift higher than larger ones.  The small particles carry a positive charge.  Larger ones, a negative charge.

Tornadoes form when strong updraughts of air rise in a funnel shape.  The air touching the earth moves slower than air above it.  This causes the air to 'roll over' and get sucked up, rotating through the inside of the cloud.

Electrical energy begins to build up in thunderclouds as small ice particles lift higher than larger ones. The small particles carry a positive charge. Larger ones, a negative charger.

Thunderstorms form when a large temperature difference occurs in a vertical column in the atmosphere.

What is it? Impact/Examples:
The impact of extreme weather could be severe. Lightning could strike things and lead to ignition. Tornadoes could also pick things up and throw them elsewhere, destroying everything in it's path. Thunderstorms could cause flooding and things to be knocked over. Tsunami's could destroy things in their path and could lead to flooding and high winds.
Examples:
Lightning, thunderstorms, tornadoes, cyclones, tsunamis.

The weather maps we see on T.V and in the newspaper are called "surface charts".  The lines and symbols represent weather patterns on earth.

The lines on the weather are called "isobars".  The numbers on the lines show the air pressure.

Areas of high pressure are marked with a 'H' and this represents 'fine' weather with few clouds.  Wind on edge of 'H' can be strong.

Low pressure areas are marked with a 'L'. Low pressure areas force wind inwards. These winds push the warm air up like a funnel and cool air rushes in to replace it. As the warm air rises it cools, forming water vapour and then clouds, leading to rain.

The sun warms up the land and sea. This heat radiates upwards. As the warm air rises it expands. As it expands, it cools down. The now colder air becomes denser and sinks back to earth. We experience this circulation of air as wind.

if the temperature is below freezing the water droplets stick together and from ice crystals.  Same as hail but without the wind forcing it into the cloud.

# data[].attributes.body
If the temperature in the atmosphere is freezing the water vapour forms into ice which drops down from the clouds as hail.  Wind gusts push the snow back into the clouds multiple times, breaking it into hailstones.

As water vapour evaporates into the air, it joins together with other water droplets to form clouds.  When the clouds are too heavy the water vapour falls as rain.
